The Pro Comp Nitro Kit (2″ rear, 3″ front) is a durable leveling kit for the 5th Gen 4Runner. Unlike simpler kits in the $100-$200 range that only include front spacers, this kit includes 2″ rear coil spring spacers and 3″ front strut spacers for added robustness.

The Pro Comp coil spring and strut spacer kit includes heavy-duty blocks and hardware, with E-coated U-bolts and zinc-plated nuts. It’s easy to install and can be reversed to return to stock height.
This kit balances affordability and function, sitting between basic leveling kits and pricier lift kits with advanced shocks. For most drivers, it offers plenty of clearance for daily or light off-road use.

Why a Leveling Kit Instead of a Lift Kit?
A leveling kit lets you fit larger wheels and tires without rubbing and eliminates the factory raked look (nose slanted down). It’s a cost-effective alternative to a suspension lift kit, which is typically designed for serious off-roading.
The primary reason to choose a leveling kit is affordability. High-quality suspension kits can cost $2,000 or more ($3,000 for an Icon setup), while a leveling kit like the Pro Comp is around $350.
For serious off-roading, invest in a suspension kit. For light trails and daily driving, a leveling kit is a practical choice. Leveling kits are also much easier to install compared to full suspension kits with upper control arms.
What’s inside the Box?
When you unbox the Pro Comp leveling kit, the quality is immediately apparent. The strut spacers, coil spacers, and hardware are securely packaged and individually wrapped. The kit also includes a full-color instruction manual, though we plan to provide even better instructions in a future post.

Will this fit my 2020 4Runner TRD pro?
Amazon states that this will NOT fit the 2021 4Runner trail, is this true?
hey brenen- or anyone with leveling kit experience. I was hoping to do 3″F 2″R leveling kit- on my 18 SR5- with adding 285-70-17. My tire shop was afraid that adding the 3″ leveling kit it would be too tall and would wear out my ball joints in less than a year. Is this a risk???
I have been running the ProComp 3″ leveling kit on my 2016 4Runner with 33″ tires and have have had no wear issues (ball joints or tires) and I am at 40K miles. Toyota actually had the ProComp leveling kit along with ProComp 18″ wheels and ProComp tires installed on a new SR5 and included all the aftermarket parts in the 3 year/36,000 mile warranty.
I haven’t been able to find it anywhere in the comments or discussion yet, but I purchased this kit and I don’t see anywhere in the instructions provided with the kit, on YouTube videos or in your instructions about whether all of the hardware included in this kit is used for a 4runner. I have a 2017 SR5 and I know it will fit after checking with the manufacturer, however I can’t find anything about where and how to install all of the hardware provided except for the strut spacers and rear coil spacers and two of the front diff/skid plate spacers. Am I missing something? Do I not need everything included in the kit?
Will this work on my 2012 trail edition?
With this kit fit a 2020 off road premium?
If anyone stumbles on this article like I did and is looking for a good “budget” lift.
Here’s what I wound up doing based off the info i got from this site. I went with the pro comp front lift only out of this kit.
I also came across another article on here about the 6112/5160 bilstein lift (just search for it). So, I followed the article recommendation out of that write-up and did the Icon Spring/Bilstein shock in the rear.
Frankensteined the two and wound up with a pretty good lift on a budget.

and
https://trail4runner.com/2018/07/03/bilstein-6112-5100-install-5th-gen-4runner/
If you ever want to upgrade the front in the future to the 6112, you’re halfway there already.
For my purposes it came out great.
To the site admins – Thanks for the information. Great resources here for all things 4R!
I really want to install this on my 2016 SR5 Premium. I trust Brenan and his expertise but am truly debating between two variants of what seems to be the same product. Either this Pro Comp 3F/2R Spacer/Leveling kit or the Rough Country 3F/2R Spacer/Leveling kit. Where I am hung up is that the Rough Country has additional shocks in the kit and am wondering if that provides a softer/smoother ride?
Will this work on an 2018 TRD Offroad w/KDSS
There is no reason why it shouldn’t. Pro Comp may need to update their product page to reflect fitment. As always reach out to them directly to ensure fitment.
Can i use this kit on my 2018 trd off road premium with everything stock and after installing the kit, I’m planning to put 285/70 R17 . Does this effect my smooth ride or braking ? and any huge mileage difference ?
The level-kit is probably compatible with your stock 2018 4R but your ride quality will see a reduction. You may see an increase in body roll/nose dive and a reduction in brake performance. Not a huge mileage difference at all (1-2 mpg maybe).
Thank you for the reply . So if i still want the same ride quality what would you recommend .
Im confused why this wouldnt fit a 2018 TRD Off Road no KDSS
It probably does fit, they just have not confirmed with new models as of yet. It may take awhile for major sites and manufacturer sites to update the fitment profiles.
Quick question. No one seems to say anything about realignment after installing this kit. The way I’m thinking about it I would think an alignment would be required after install. Am I correct?
Alignment is not needed but wouldn’t hurt.
I have this kit on my 2017 4Runner Limited. I do not recommend this kit for anyone. My car feels like a boat on the FWY.You cannot make sudden lane changes with this kit. Going over a hump on the road the rear slams really hard like as if there were no shocks in the rear. This kit was not made to work with stock suspension.
I am running this Kit with Bilstein Shocks and trust me that made the kit much more drivable and more effective offroad.
Which bilstein shocks did you use? Do the 5100’s work with this kit, and if so where did you set the adjustment to? Thanks
does this work with KDSS?
Yes.
I have read some things about the rear spring spacers not working well with 2017-18, I read that you can modify the rear spacer to fit (assuming the diameter was different where it fits into the spring) have you come across this at all?
Matt,
Interesting. Where did you read this on rear spring spacers for the 2017-18 4runner, and what exactly did it say? We have seen a few guys on here installing spacer kits on their 2017 4Runner with no issues. Can’t say the same for 2018, but nothing has changed that I know of, so it would be interesting to see someone out there with a 2018 do an install just to confirm. If you hear anything else, let us know.
Is this kit works for 2017 4 runner limited?
Nadan,
The best way to make sure the kit is compatible with your 4Runner is to check with the manufacturer. Or, head over to the link provided in the description and enter in your vehicle. This will show you if the kit works. I am not 100% sure if the kit works on a 2017 Limited 4Runner. You probably ok to grab the kit but always double check before buying anything.
With this work with the RWD version too? I’m not trying to throw a serious lift on something that isnt going to be seeing intense trails.
Preston,
This leveling kit is compatible with all versions of the 4Runner. You should always double check with the sellers before buying. By RWD, did you mean 4WD or Rear-Wheel Drive?
These numbers are a little confusing. I currently have a 1.5 inch rake on my 2016 4runner SR5. This kit will make it perfectly level? And what do you mean by occasional trail use with a spacer kit is okay? I don’t do anything major, like tires coming off the ground, but I do travel off road frequently. Friends say I should avoid the spacer due to suspension or wheel having less travel.
Matt,
Sorry, I should have more specific there. Occasional trail use means general fire roads, light-weight trails, easy to moderate trails, etc. If you are not hammering your suspension off-road often, like heading to Moab or doing super rocky/boulder terrain, then a spacer kit is perfectly fine. There is nothing wrong with a spacer kit but your friends are right. You will have less travel or less suspension flex when you are on the trail. If you can afford an upgraded suspension, like the Icon Stage 2 Suspension, OME Suspension, Bilstein Suspension or something similar, it would obviously be better to go this route. But, if you are not planning for anything super aggressive, a spacer kit will work just fine. Also, an upgraded suspension is just more comfortable and easier on the 4Runner off-road/ on-road. With an aftermarket suspension, you will have more travel, more flex and improved on-road performance like less body roll, less nose-dive, and just better all-around driving performance. Hope this helps Matt.
with the PRO COMP NITRO 3 INCH REAR AND 2 INCH FRONT LEVELING LIFT KIT – 65210K what is the max tire size i can install on a 2017 4runner trd off road
Richard,
With any and all lift kits, suspension kits and level kits at 3″, the max tire size you can run without trimming anything is 33″.
That is a 285/70R17. This is what people typically run with a 3″ suspension lift or leveling kit on their 5th Gen 4Runner.
